“There are particular facts that are strong that Mr. Jackson intentionally gave her an overdose,” said Jennings County prosecutor Alan Marshall.

Mann says the night her sister died, Jackson was acting strange.

“He gave us about two or three different stories on what had happened, on what was going on. He couldn’t keep his story straight that night,” Mann said.

Jackson was initially charged with Louden’s murder, but on Monday that charge was dropped. If convicted on federal drug charges, Jackson could spend the rest of his life behind bars.

“There is a high likelihood of him getting more jail time (this way) he is in better hands with the U.S. Attorney’s Office,” said Marshall.

Federal authorities also believe Jackson played a key role in a 26-person drug ring that had ties to drug cartels in Mexico.

“By dismantling this operation, we have been able to stop a major flow of meth into our community,” added Marshall.

“It was even bigger than I thought it was going to be," said Mann.

Mann says she knew Jackson was bad news, but she did not see this coming.

“But with the entire investigation, I was completely unaware that that was all being tied in together,”Mann said of the massive operation.

Mann believes meth is a problem in Jennings County, but thinks local and state authorities are doing everything they can to stop the flow. Now, she wants to see all of those allegedly involved to pay the price.

“I’d like to see all of them, everyone that was indicted, all of them to face serious charges for the drugs they brought in the county because there are too many young people dying,” said Mann. “It’s not a joke, it’s not a game, it’s time to stop,”
